Something equally unacceptable happened in London last night. According to a Southbank Centre statement: “An intruder forced his way into the Royal Festival Hall auditorium and onto the stage during last night’s concert and attempted to disrupt the performance by filming himself on his mobile phone.”

What the statement doesn’t say is that the man came on stage as Ádám Fischer was conducting the Orchestra of the Age of Enlightenment in the finale of Dvo?ák’s New World Symphony. I know what you’re thinking. Never since its principal theme was used to sell Hovis bread has anything so terrible happened to the New World Symphony. Hasn’t Dvo?ák suffered enough?

My colleague Tim Ashley reports in his review that Fischer shot the intruder a look of “quizzical amazement”, and the Southbank statement notes “the concert continued without pause”. I am in awe: I couldn’t conduct Dvo?ák to save my life, still less shoot anyone a look of quizzical amazement at the same time.
